Description

Technical Field

[0001] This utility model relates to the technical field of printing equipment auxiliary equipment, specifically a mechanized cleaning device for printing plate of a printing press. Background Technology

[0002] In the printing industry, printing plates on printing presses are prone to accumulating ink residue, paper scraps, and other impurities on their surface during long-term use. If not cleaned in time, these impurities can seriously affect the quality of subsequent printed products, leading to problems such as misregistration and blurry patterns.

[0003] During the cleaning process, two rotating brushes are used for cleaning. After the cleaning agent is sprayed, the rotating brushes fling the cleaning agent out. While airflow can limit this flinging, the cleaning agent cannot be quickly transported to other areas below the brushes to enhance cleaning efficiency by combining airflow with the cleaning process. Therefore, those skilled in the art have provided a mechanized cleaning device for printing plates to solve the aforementioned problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a mechanized cleaning device for printing plates of printing presses.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A mechanized cleaning device for printing plates of a printing press includes:

[0007] Sliding frame;

[0008] Two brush plates are synchronously rotated on the sliding frame, and the two brush plates rotate in opposite directions. The two brush plates form two "V" shaped first and second angle areas, wherein the brush plate in the first angle area rotates towards the closest point of the two brush plates.

[0009] Side grooves are provided on the periphery of the brush plate;

[0010] A water outlet pipe is installed on the sliding frame, with its outlet facing the first included angle area;

[0011] The air duct is mounted on the sliding frame, with its air outlet facing the second included angle area;

[0012] When the brush plate travels along the direction from the air duct to the water outlet pipe, the side groove in the first angle area guides the flow of the cleaning agent sprayed from the water outlet pipe, the air blown out of the air duct restricts the flow of the cleaning agent in the side groove in the second angle area, and the air blown out of the air duct is conducted to both sides through the side groove.

[0013] Preferably, the two brush plates are in contact, and the water outlet pipe and the air duct are located on the common tangential surface of the two brush plate contact positions.

[0014] Preferably, the spray center point of the water outlet pipe is located at half the height of the deformable part of the brush plate.

[0015] Preferably, the sliding frame is provided with a detergent tank, which is connected to the water outlet pipe via a water pump; the sliding frame is also provided with a fan, the output end of which is connected to the air duct.

[0016] Preferably, the side groove is arc-shaped, and the opening direction of the side groove is towards the water outlet pipe when it is within the first included angle area.

[0017] In summary, this utility model has the following beneficial technical effects:

[0018] 1. During the cleaning process, the high-pressure airflow blown out by the air duct can restrict the outflow of cleaning agent in the inner groove of the second angle area, prevent the cleaning agent from being thrown out by the centrifugal force generated by the rotation of the brush plate, improve the utilization rate of the cleaning agent, and at the same time enable the cleaning agent to be transported to a more distant cleaning area with the rotation of the brush plate.

[0019] 2. High-pressure airflow can prevent the cleaning liquid sprayed from the water outlet pipe from flowing from the first corner area to the second corner area, ensuring that the cleaning liquid is concentrated in the first corner area and the contact area between the brush plate and the printing plate, which facilitates the delivery of cleaning liquid and further improves the cleaning effect;

[0020] 3. The air blown out by the air duct is carried and reflected by the side groove and conducted to both sides. After the brush plate completes the rotation cleaning of the printing plate, it can quickly dry the residual cleaning liquid on the surface of the printing plate and speed up the drying speed of the printing plate.

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] A mechanized cleaning device for printing plates of a printing press, referring to Figure 1-3 ,include:

[0028] The sliding frame 1 is equipped with rollers at the bottom, which allow the entire cleaning device to slide along the length of the printing plate, facilitating thorough cleaning of the plate surface. The sliding frame 1 can also be equipped with lifting mechanisms such as cylinders and telescopic rods, allowing adjustment of the overall height of the sliding frame 1 to accommodate printing plates of different models and heights, thus improving the device's versatility.

[0029] Brush plate 2 is made of elastic material and has a certain degree of deformability. Two brush plates 2 are synchronously rotated on the sliding frame 1 and rotate in opposite directions. Specifically, a drive motor is installed on the sliding frame 1, and the output end of the drive motor is connected to a drive gear. Driven gears are installed on the rotating shafts of the two brush plates 2 respectively. The two driven gears mesh with each other, and the drive gear meshes with one of the driven gears. The drive motor drives the drive gear to rotate, which in turn drives the two driven gears and the brush plates 2 to rotate in opposite directions, ensuring that the two brush plates 2 rotate in opposite directions.

[0030] Two “V” shaped first and second angle areas are formed between the two brush plates 2. In the first angle area, the brush plate 2 rotates towards the closest point of the two brush plates 2, and a side groove 21 is provided on the periphery of the brush plate 2.

[0031] The side channel 21 is arc-shaped, and the opening direction of the side channel 21 is towards the water outlet pipe 3 when it is in the first included angle area. This structural design makes it easy for the side channel 21 to receive the cleaning agent sprayed from the water outlet pipe 3.

[0032] The water outlet pipe 3 is fixedly installed on the sliding frame 1. Its water inlet end is connected to the detergent tank 31 through a pipe, and a water pump is installed on the pipe. The water pump provides power for the delivery of detergent. The output power of the water pump can be adjusted according to the cleaning needs, thereby controlling the amount of detergent sprayed from the water outlet pipe 3. Its outlet faces the first included angle area.

[0033] The air duct 4 is installed on the sliding frame 1, with its air inlet end connected to the output end of the fan 41, and its air outlet facing the second included angle area.

[0034] The brush plate 2 travels along the direction from the air duct 4 to the water outlet pipe 3. The side groove 21 in the first angle zone guides the flow of cleaning agent sprayed from the water outlet pipe 3. The rotation of the brush plate 2 itself also drives the cleaning agent to rotate, which can enhance the flow of cleaning agent and improve cleaning efficiency. This allows the cleaning agent to flow to different positions below the brush plate 2 during rotation, increasing the cleaning agent's surface area. Because the side groove 21 carries a certain amount of cleaning agent, the air blown out of the air duct 4 can restrict the flow of cleaning agent in the side groove 21 in the second angle zone, preventing the cleaning agent from being thrown out due to centrifugal force, and allowing the cleaning agent to be transported a longer distance. Since the air blown out of the air duct 4 is directed towards the second angle zone, it can also prevent the cleaning liquid sprayed from the water outlet pipe 3 from flowing from the first angle zone to the second angle zone, allowing the accumulated cleaning agent to enter the side groove 21 to a greater extent. The air blown out of the air duct 4 is carried and reflected by the side groove 21 and conducted to both sides, which can speed up the drying speed after the brush plate 2 has finished rotating and cleaning.

[0035] Two brush plates 2 are in contact, and the water outlet pipe 3 and air duct 4 are located on the common tangential surface of the contact point between the two brush plates 2. This allows the spray direction of the cleaning agent to work synergistically with the blowing direction of the airflow, ensuring that both the cleaning liquid and the airflow can accurately act on the key cleaning areas of the brush plates 2 and the printing plate, maximizing the cleaning effect.

[0036] Furthermore, the spray center point of the water outlet pipe 3 is located at half the height of the deformable part of the brush plate 2. This spray position design allows the cleaning agent to be accurately sprayed onto the surface of the brush plate 2 within the first included angle area. Simultaneously, in conjunction with the rotation of the brush plate 2 and the guidance of the arc-shaped side groove 21, the cleaning agent can flow to different positions below the brush plate 2 as the brush plate 2 rotates, increasing the coverage area of ​​the cleaning agent on the printing plate surface, enhancing the flow effect of the cleaning agent, and improving cleaning efficiency.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
